Thiel Boots: Overhead Rates & Over or Under Applied Overhead

Expected to sell 10,000 pairs of boot
est. of production employees will work 10,000
production equipment to operate 8,000

A. Compute the predetermined overhead rate for Thiel using the following three cost drivers: direct labors hours,direct labor dollars, and machine hours.
B. If actual labor costs were $170,000 for 10,500 direct labor hours and actual machine hours used were 7,800, what would be the applied overhead, using the three predetermined overhead rates computed in part A?
C. Compute the amount of over- or underapplied overhead, assuming that actual over-head is $229,000. You should assume that overhead was applied as computed from B.
